Gravitational Torsion Balance and He–Ne–Laser


Gravitational Torsion Balance and He–Ne–Laser demonstrates gravitational attraction between two bodies and determines the gravitational constant.

  • Two Small V-Shape Stand Bases
  • Rotatable Clamp
  • Two Self-Adhesive Scales
  • Large Lead Balls
  • Machine Determine Gravitational Constant
For demonstrating gravitational attraction between two bodies and determining the gravitational constant. Highly sensitive torsion dynamometer, whose deflection can be observed and measured via a laser pointer. The torsion system consists of a bronze torsion band and a dumbbell-shaped torsion body with small lead balls and a mirror; the system is accommodated in a housing with front and rear windows, in order to shield it from interference by air currents. The housing is mounted on a stand rod, with a swiveling holder for large lead balls which are used to influence the torsion system. When the balls are displaced, the system starts oscillating slowly about its axis of rotation. Conclusions regarding the effective force between the large and small balls can be drawn from the pattern of the oscillations as well as the new state of equilibrium after the oscillations have died out

Ordering information: Complete with large lead balls and two self-adhesive scales. Lighting equipment and stand material not included. Includes Gravitation torsion balance; Stop clock, d = 21 cm; Steel tape measure, l = 2 m/78"; Stand base V-shape, small (2); Rotatable clamp; Leybold multiclamp; Stand rod 47 cm, 12 mm.

Note: A laser 'pointer' may be used/supported by a test tube holder.
